To all whom` 'Lt may concern:

Beit known that I, JEssE G. VINCENT, a citizen of the United States, residing at Detroit, -in the county of Wayne and State of Michigan, have invented certain new and useful Improvements 1n Carriage Mechanism for Adding-Machines, ofwhich the fol-- lowing is a specication, e

The present invention relates more Vparticularly to devices for facilitating the use of an adding machine f or tabulating purposes and one of the objects is to provide improvedv means,l simple in form and requiring comparatively few parts,'whereby A vide improved means of simple and durable character for automatically disabling the adding or accumulating mechanism of the machine as a result of positioning the paper carriage at a predetermined adjustment when an'amount is to be printedbut not added.

A further object'of the invention is to provide for readily interchan 'ng stop devices which determine the di erent lateral adjustments of -the Vpaper carriage for the purpose of facilitating the ada tation of the machine 'to different classes o work.

A still further object of the invention is to provide a` gage whichwill automatically take up its proper, position over the work Vwhen the platen is thrownback, such gage serving to definitely locate upon.` the paper the printing line and any columnar pointi therein.

IVith these and incidental objects in view the invention consistsin certain novel features of construction and combinations of parts the essential elements whereof are recited 'in the appended claims and preferred forms'f embodiment of which are illustrated in the accompanying drawings and described in detail hereinafter,

Of said drawings Figure l represents in left side elevation certaininterior parts of an adding machine of thewell-known Burroughs type together with' additional parts employed-'1n carrying outthe present invention (the casing ofthe machine and certain cross-shafts and rods appearing insection), and also shows in section carriage mechanism at the rear ofthe adding machine including the improvementsv of the present invention; Fig. 2 shows the carriage mechanism in rear elevation together with the adding machine to which it is applied; Fig. 3 is a detail rear view of a certain vstop device on the adding machine; Fig. 4 is an enlarged detail in horizontal section of certain connections for controlling the line spacing;

While the invention is illustrated and described in thepresent instance as applied to y an adding machine of the well-known Burroughs type exemplified in the William S. Burroughs patents Nos. 504,963 and 505,07 8, issued September l2, 1893,' it is nevertheless to be understood that the improvements of the present invention are capable of utilization in connection with adding machines of other types and some of them in fact in machines which do not possess the functions of Van adding machine;

Preliminary to a detailed description' ofV .the novel constructions for'carrying out the present invention it will be desirable to describesat'some length certain carriage mechanism vwhich ofY itself 'does not constitute subject matter of the present invention'.

In the drawings the reference numeral 1710'designates the back roughs adding'machine which is open at the upper part for the projection therethrough 'of type in theprinting operation. Secured across the back Aof this` panel is a supporting bracket 1765 formed with race'ways' of y i ball bearings for the laterally shifting paper cross rods 1700 and 1701. The usual platenroller 1798 is supported in this cradle upon a rotary shaft 17 00a and bylroclring the cradle on the shaft 1705, preferably by means of the knobs or thumb nuts 174:6, the platen may be moved into and out of printing position in rearof the above mentioned opening in the casing of the adding machine.v The paper is introduced from vthe rear between .gages 1728EL slidingly mounted upon a cross bar 1727 of the cradle, and-passes to the underside of the platen, being guided by a.-

curved plate 17 25, also carried by the cradle. The paper thence extends over the front side of the platen, where it is presented to the type a suitable. guide late 1710,EL being secured in the opening of the addingmach'ine casing, appropriately apertured for the pas- A sage of the type and of such form as to cause the .paper to hug the platen;Y When wide paper is used it passes up by the edge of said guide-plate, but a narrow strip, .such as used when simply listing'amounts andv not tabulating, w1ll be passed under the cross rod 1701 whichY carries a severing blade 1721.

' other so .as to insure the proper pressure of` .The feed pressure of the paper against the platen is produced. through the employment of several sections of rollers 17 94, each sec.

tion being movable independently of every thepaper against the platen roller throughout its' width and hence uniform advance of the paper. in a section occupies an opening in the guide plate 1725 (Fig. 9) and 1s Vjournaled in the outer ends of avr pair of arms 1711 which in turnV are journaled upon the shaft 1705 and pressed upwardly by springs 1780 enciranel of a Bur-V Each set of rollers'1794 compos' clingthe shaft and bearing at their rear ends against the underside of the cross rod 1700, while at their forward ends they embrace' pins or studson the arms 1711, respectively, (see Figs. 2 and 9) A series of collars' 17 34,

Fig. 2) one foreach arm 1711, are secured to vthe rock shaft. 1705, said collars having forwardly. projecting fingers 1712 (Fig. 9) bearing upon the upper sides of studs 1752b Vof said arms 1711,-so that by turning the said shaft, which may beV done by moving the finger lever 1724, all the pressure rollers `may. be withdrawn from contact with the Aplaten roller, when it is desired to release the paper. from `the feed pressure. This finger lever projects in rear of the 'platen at a con-' venient location for manipulation by the right hand of the operator and is, of course, secured to the shaft 1705. A forward projectionofsaid finger lever is connected by a spring 1786 witha stud on the cradle, (Fig.

18 and dotted lines, Fig. 1), said spring serving to hold the fingers 1712 normally elevated to permit the springs 1780 to have free playin pressing' the feed rollers against the platen.

Y It is quite important, *particularly in tabulating Work, tohold the platen firmly to its printing positionand to that end means are providedfor supplementing the gravity of the parts usually relied upon to maintain the proper position of the platen. plate of the cradle is formed with a downward and rearward extension 1719d (Figs. 9Y and 19) whose rear edges extend concene trically with the pivot of the cradle and One end whose side edges extend tangentially thereof.

A lever 17132L is mounted lto turn upon the left handend of the rockshaft 1703 and a relatively strong spring 17 88 connects the forwardly extending arm of said lever with a stud on the end plate ofthe carriage, for. p

`the purpose of forcibly thrusting the rearwardly extendingarm of the lever in a forward direction. vThis rearwardly extending arm is formed as -a hanger at its outer end and an'antifriction roller 1741a'is mounted in this hanger and. bears against the edges of. the rearward extension 17191. In the normal position of parts with the cradle rocked forwardly, said roller bears against the lower tangential edge of said extension* and thereby causes the spring 1783 to exert a pressure v.

holding the platen to its printingposition. When the cradle isthrwn back to remove thev platen from its printing position. the tension of. this spring must, of course, be overcome as the lug or extension 1719I forces its way past the roller. -However, as soonv as the concentric edge of the lug passes out yof contact with the roller. the latter'will be pressed against the upper tangential'edge of said l-ug so that the spring Y1783 then exerts itself to hold the cradle in its extreme rearward position.` It will be seen that saidv moese' spring serves as a means for automatically completlng the rockmg movement of the cradle in coming to its forward as well as its rearward position. These positions areI determined by the abutment of radial shoulders 1719e on the end plates of the cradle against laterally projecting flanges 17171 ofa spring 1782 connected 'at one end thereto` and at the other end lto a stud projecting from said end plate, as shown in Fie#l 19.

rEhe usual knob or thumb piece 1795 (Fig. 5) secured to the opposite .end of the platen journal serves for turning the platen-roller back and forth by hand.

The line spacing mechanism (Figs. 1, 2 and 18) comprises a ratchet wheel 1728 secured to the platen spindle 17 00a between the knob 1795 and the right hand end plate of the cradle, and a pawl 1722 carried by apair of arms 1713 mounted to turn vupon'said journal, the pawl being held in engagement with the ratchet wheel `by a spring 1787 connected at one end thereto and at the other end to one of said arms.f A stud 1758a forming the pivotal connection between the pawl and its supporting arms also constitutes a pivotal connection between said 'arms and a link or pitman 17 22a curved at itsiofwer end in the arm of circle described about the rock shaft 1703. This curved part of?l the link or pitman is formed with a longitudinal slot 1722d curved in the same arc and an abutment or tappet piece 1747 occupies said curved slotv and -is Aadjustable*lengthwise thereof to vary the extent of the line spac- An arm 1724 secured to the rock shaft 1703 carries a screw stud 1760afat its uter end occupying the slot 17221. AThis screw stud acting against the tappet piece 1747 will thrust' the `link or pitman 1722a upwardly and draw the pawl 1722 over one or, more teeth of the ratchet wheel 1728 according to the adjustment of said tappet piece. On the return stroke of the arm 1724 the said screw stud-acting against theqlower end of the slot in the pitman draws the latter down and thereby causes the pawl 1722 to advance` the platen a distance corresponding' with the length of the tooth or teeth of the ratchet wheel over which the pawl has been retracted. i

The oscillations of th'e actuating arm 1724 are produced through the medium of a series of forwardly extending arms 1723 secured to the rock shaft 1703 and united at their outer ends in a strip which enters the longitudinal slot of a rod 1706insuch manner as known manner.

' longitudinally ends upon a screw stud 17 53h of a standardl 765 within the adding machine casing, as

'shown in Fig. 9. The outer end of the forward arm of said lever carries a roll 1720ZL occupying a cam slot 121d of a plate 121 secured to arock shaft 100n of the' adding machine, which rock shaft receives. an oscillation in every operation of said machine resulting through co-actionv of the cam slot with the roll, in producing vibration of the lever and consequentl reciprocation of the bar 1723a which in turn may produce vibration in the'shaft 1703 and the arm 1724.

Lateral shifting of the carriage does not' dis- 4 turb these connections because the rod 1706 is arranged to slidebetween the jaws 1723b and 1724b'and maintain its operativerelation'thereto under any lateral adjustment of the carriage.

The means here shown for idetermining the lateral position of the carriage are of the following description. On a pair of posts i 1716b projecting from the panel 1710 (Fig.

6) there is supported a cross bar 1716 shouldered on its upper edge at the center, (Fig. 3), and the before mentioned rock shaft 1704 carries a series of stop fingers 17 92 and 17 92a adjustable lengthwise thereof and adapted to ,be fixed at different positions by means of set screws 1762 engaging a longitudinal slotl or groove 1704b in said shaft, any one of these stop fingers being adapted to engage the shoulder of the cross bar 1716 to determine the lateral position of the carriage. The latter is drawn to the left by a clock spring` 1788 within a drum 1768 rotating in a stud 1768b supported within the casing of the adding machine by a bracket 17195, one end of the spring being secured to the drum and the other to the stud. A steel strap or band 1768a is secured at one end to the carriage 1767 and at the other end to said drum upon which said. band Winds as the carriage is `impelledy by the spring in a well- For the purposesl of the present invention' the jaws which embrace the round rod 17 06 of the line spacing mechanisin are made separable, the Iupper jaw 1724'J being part of a slide bar 1724* slotted to engage vthe same 'screw studs 1723c which guide. the slide bar 1723a but the latter may move independently of the slide bar 1724, ltivotally mounted upon the same pin 1715b which connects the slide 1.723a andthe lever 17 2Q, is a dog 1715aL connected by'a spiral spring 1715c with said slide bar, said/spring tending to"force the lower end of the dog which. is 'in' the form of a catcl1"1715 f i nto engagement with the top side or shoulder cfa projection 1724c at the lower end of the slide'bar 1724a.-

When thi'scatchis so engaged With said projection it 'will be obvious v'that-the two slide bars vwill moveas one andfeifecttheline spacing through the connections'- previously described., On the other hand if this catch" is disengaged from the projection the slide" vbar .1723 will descend without carrying.

As before stated the stop-fingers are v'longitudinally adjustable -on therod'l704 land as will hereinafter 'appear these stop fingers are removable from the rod, so that j various arrangements vand adjiistnients .of thev fingers can be brought about ,to suit different 'kinds of tabulat-in'g, work to' bev done on the machine.

The above described con'struction'of dog carriage and permitting the spring tdishift it to the next columnar position to the'left.

Of course as the slide bar 1723a is movedv the carriage shifted later! downwardly by theilever 1720-v the dog-is carried along with it. The displacement of the dog by itsfcontact with'the stop finger 1792 brings thef end of the -latter'to Abear against the "central portion ofthedog under the pressure of the spring 17150. In the downward-movement ofthe dogits" upper end passes below the stop ingerand said springl carries the dog under the stop finger so that upon the upward -movement of. the

slide bar 17 23a and consequently of the-dog thefupper end of 4theA latter'v acting 'against the under-edge ofthe stop'linger'will lift A the-latter outfvof engagement withthe shoulder of the stop plat e ',1716 L whereupon. the

carriage willbeshifted .until the next stop finger to the right .comesup against 'said shoulder. As thefdog continues its. upward.' movement its lower end-portion or catch 1715f will slide-over the inclined baclof the catch projection 1724c and thenA be drawn into engagement with the top shoulder thereof. Should the- .tabulati'ng work be ofsuch a characteras tfc'all for line'spacingv at the neXtoperation, then the next' stop nger to the rightwill be one of the shorter kind and consequently in the reciprocation of the'slide bar 1723a the line spacing-mechanfism will beoperated', the parts thereofmaintaining the relation illustrated in Fig. 10

As 'tol the means here'shown for auto 'matically disabling the accumulating mech-V 'anismi'twi'll first be desirable topoint out some' of the parts in the regular Burroughs ",'machine through xwhich accumulation of 'it'emsset .up on the key-board is brought about. A .Referring to Fig. 1 the reference numeral".291-designates ythe-usual amount keys which control the extent of movement of racks'610 normally upheld bylatehes 415.

Theadidirifrl; wheels-to which :these racks .impart movement are vsupported in ya rocking-frame 910 which is connected through fa'vpi'tman 914 with athree-'armed lever 913 8.21 pivotally mounted o'n the end of alever 1813;; For a detailed description of these "partsand those .with 4which they coperate -in performance .of the. usual functions of the Burroughs machine, reference may' be cation'to statethat the' lever 813 is rocked'.

back and forth in each operation offthema- .1 chine and 'its pawl 821 acting alternately uponthe pins of the three-armed'lever 913'Y will rock the latter back and forth thereby transmittingmovement through the medium of the'pitman 914 to theframewhich carries the Aadding wheels. Normally the latter are .in mes'hwith the racks A610 but-at the com- 'mencement of an operation ofthe adding i said racks movev downward to positions decarrying studs to be acted upon by a pawl 110 termined bythe depressedkeys 291. The

downward movement of the racks is accompanied by movement ofv levers 611 so l.that type on plates 618 at the rear of such levers will be brought to the printing line in correspondence with the depressed keys. After the printing takes placein the manner set forth in said Patent No. 505,078, the lever S13 starts forward and the adding wheels are brought into mesh -with the racks 610 so that when the latter move upward to normal position the adding wheels will be f .turned to the proper extent.

that in many kinds of tabulating work it is desired' to print` numbers in a column withoutaccumulating the total thereof. In the Vpresent 'instance the stop fingers 1792 and 1792.a are formed with bosses 1,792" tapped-to receive screw studs 1792c upon which are mounted rollers 1744r11 as shown in Fig. 8. lA lstop finger willzhave this roller stud depending from it or not according to whether or not 'the amount to be printed when the carriage is inthe position Vdetermined by such stop finger is to be excluded from the accumulation. The studs with their rollers can be readily attached `to or removed from the stop fingers so that varying characters of tabulatingwork can be accommodated.

A horizontally vibrating lever 1717b is pivoted" intermediate its ends to a bracketv 1718b on .the back of the adding machine and one Aarm of this lever 'is formed with a laterally projectin nose 1717C (Fig. 6) for engagement with t 1e roller 17441L of any stop finger carrying this attachment. The other arm of said lever 1717 b is jointed to one end of a link 1717d which is in turn jointed to the depending arm of a bell crank lever 1713e whose horizontally extending arm projects above the path of movement of Aa laterally projecting stud 821a on the pawl 821. This bell crank lever is pivoted on a suitable support within the adding machine .and is normally held forward as to'its depending armV and upward as to its horizontal arm by a spring 1714'3 connected at one end to the link 1717d and at the other end to a fixed stud 1717f which constitutes al stop'tolimit the rearward movement of the link. This spring tends to thrust the nose 1717c of the lever 1717b into the path of the roller 17 44%. Thus, when the lateral shifting of the aper carriage bringsthe stop finger carrying said roller up against the fixed abutment determining the position of the carriage; the roller acts against said nose, and thereby rocks the lever 1717b andl holds it displaced from normal position during the ensuing operation of the adding machine. This results in rocking the bell crank lever 1713c and lowering its horizontal arm into the path of the stud 821a on the awl 821. Therefore said pawl is prevented rom assuming its coperative relation with the rear pin or` stud of the three-armed lever 913 and consequently when the lever 8 13 is vswung forward it fails to return said threearmed lever to its normal position and the adding wheels remain out of mesh with the .racks 610. It follows that said racks return to normal without actuating said wheels and the amount which has been printed is not accumulated. Of course when' the lateral position of the carriage 'is determined by a stop finger from which the roller stud is removed, the accumulationwill take place as usual.

It has been already mentioned that provision is made for removing the stop fingers 'from the rod 1704. In this same connection provision is made 4for interchanging the rod with one designed to provide for changing the lateral adjustment of the carriage by hand, omitting the devices for automatically construction of this modified character is illustrated together with `constructions for facilitating the interchanging of stop rods. The modified stop rod 1709 is flattened on one side for the attachment by suitable screws of arms or lugs of a strip or plate 1712b formed with the down-turned flange 1712e notched at different points throughout its length as shown at 17121. The cross bar or plate 1716EL heretofore mentioned is provided withl a rearwardly projecting lug 1763i preferably square in cross section for engagement with one or another of the notches 17121. It will be .seenv that by rocking the rod lthe notched strip may be disengaged from said lug and the carriage moved to anylateral position desired. In the present instanceas hereinafter inore particularly explained the enga ement between the notched strip and the ug is enforced by spring pressure.

The following described construction, illustrated in detail in Figs. 16 and 17, provides for the interchanging of the stop rods 1704 and 1709. Each rod is formed at the right-hand end with a cross slot 1742e and at the left-hand end with a trunnion 1704. The cross slot is adapted to engage a tongue 1742d on the end of a shouldered stub shaft '1742 and the trunnion is adapted to engage a step bearing in the headed end of a screw 1740. The stub shaft 1742 is journaled in a sleeve 1 743 secured in the right-hand end plate 1717R of the paper carriage, said vshifting the same. In Figs. 12 to i17 a stop 7 60 "gagement sleeve being interiorly shoulderedto vprevent lateral movement -of the stub shaft.'

The screw 1740 engages the tapped' opening of a somewhat' similar sleeve 1740asecured in` the left.- hand end plate" 17171' of the 'paper carriage.A V This last-named sleeve is turnedout to provide forthe head ofA the screw slidingv therein and said screw 1s .formed with. a stem 1740b to which is fas- 10 tened a. knob or thumb piece 1741.

The rocking o the stop rod by'- hand is of course necessary inthe construction shown in. Figs. 12 to15 but it isV also desirable in the previously described construction where 20 the devices. for automatically rocking the -rod VVare employed` The same manipulative devices serve in either case, being illustrated 'in Fig; 1 as applied to the saine parts which in Figs. 12 .to 15 hold the Vstop rod 1709.

25 These devices Vcomprise a collar 1730afse.

.link 1715?L coupled to the rearwardly extending portion fof 'said plate, and a lever 1726 pivoted on the rock-shaft 1703 and jointed'at -its forward end Ato said link. ,The

rearwardly and upwardly extending arm' of this lever terminates at a convenient location in a finger-piece 1745 and it IWill be 35 seen'that by forward pressure upon the latf ter the stub shaft 1742-will be rocked inja' direction to disengage the stop devices..

It-is to be noted that e-in this V construction can be freelyA moved tothe right7 the stop fingers riding over the inclined vedge of the cross .b ar 1716a elongated carriage can be thrown to the right without' necessarily manipulating the lever 1726.
